(DEA). The review covers topics that we hope will be of special
interest to th ...

Empirical evidence indicates that environmental fluctuations have important effects on fisheries
production. However, existing analytical solutions of stochastic fisheries models have been
produced only under highly si ...

Jointly with kilowatt-hours (kWh), electric power plants also produce CO₂, NO[subscript x], and SO₂. In this paper, we apply an environmental production model based on data envelopment analysis (DEA) to compare the produ ...

the theoretical gains from trade would be realized. We will employ a methodology that calculates the potenti ...
